5.2 Signal Descriptions
72
0ADJ
Zero adjustment executes once when the
0ADJ
signal transitions from
High to Low.
PRINT
The current measurement value prints when the
PRINT
signal
transitions from High to Low.
MANU
When the MANU comparator mode is selected, comparator judgment
is enabled while the
MANU
signal is Low.
™
See Section 4.1.4 Comparator Execution Mode Setting (Page 44).
IN0 to IN4
The
TRIG
,
CAL
,
0ADJ
,
PRINT
and
MANU
signals can also serve as
general-purpose input terminals, read with the :IO:IN? command.
™
See Section EXT I/O Input (Page 134).
5.2.3 Output Signals
ERR
Indicates a measurement fault.
The Synchronous ERR output setting causes ERR output to be
synchronous with EOC output, while with the Asynchronous ERR
output setting causes ERR output to follow actual (asynchronous)
contact of the probes with the test object.
™
See Section 5.2.4 ERR Output (Page 73).
INDEX
The INDEX signal is output during the Trigger Wait, Delay, Self-
Calibration and Calculation states.
This signal is not output while measuring the resistance of test objects.
This signal transitions from Off to On to indicate that the test object
can be removed.
EOC
This signal indicates the end of a measurement (End-Of-Conversion).
This signal indicates when comparator judgment results and ERR
output (when SYNC is enabled) are available.
R-Hi, R-IN, R-Lo
V-Hi, V-IN, V-Lo
These are the results of comparator decision.
AND
This signal indicates when both resistance and voltage judgment
results are IN (
Ω
V mode).
In the
Ω
and V modes, this signal is the same as R-IN and V-IN
outputs, respectively.
OUT0 to OUT9
The output signals are controlled by the
:IO:OUT
command.
™
See Section EXT I/O Output (Page 134).
INT.GND
This is the instrument's internal ground.
• I/O signals should not be used while measurement settings have
been changed.
• The EOC and INDEX signals are initialized (ON) at power on.
• If it is not necessary to change the measurement conditions, set
LOAD0
through
LOAD6
to either Hi or Lo.
